I always had a good experience with Phabricator, especially its customization/dashboards. Wikimedia still uses it[1]. [1]: https://phabricator.wikimedia.org/
It's a shame that Wikimedia couldn't donate money to Phabricator for it to stay alive, considering it raised ~$30mil in 2019.
It doesn’t seem like there is much interest in finding ways to keep phacility alive.
Note: I work on phabricator at Wikimedia. My opinions do not necessarily match those of the foundation and I’m speaking from personal experience not from any position of authority.
